Sex differences in the neural processing of decision-making are of high interest as they may have pronounced effects on reward- and addiction-related processes. In these, the neurotransmitter dopamine plays a central role by modulating the responsiveness of the reward circuitry. The present functional magnetic resonance imaging study aimed to explore sex and dopamine transmission interactions in decision-making. 172 subjects (111 women) performed a behavioral self-control task assessing reward-related activation during acceptance and rejection of conditioned rewards. Participants were genotyped for six key genetic polymorphisms in the dopamine system that have previously been associated with individual differences in reward sensitivity or dopaminergic transmission in the human striatum, such as rs7118900 (dopamine receptor D2 (DRD2) Taq1A), rs1554929 (DRD2 C957T), rs907094 (DARPP-32), rs12364283 (DRD2), rs6278 (DRD2), and rs107656 (DRD2). The selected polymorphisms were combined in a so-called multilocus genetic composite (MGC) score reflecting the additive effect of different alleles conferring relative increased dopamine transmission in every individual. We successfully demonstrated that reward-related activation in the ventral striatum and ventral tegmental area (VTA) was significantly modulated by biologically informed MGC profiles and sex. When comparing men and women with low MGC profiles that may indicate lower dopamine transmission, only women displayed a reduced down-regulation of activation in the mesolimbic system during reward rejection and additionally, a significant non-linear u-shape relationship between MGC score and VTA activation. Taken together, by integrating neuroimaging and genetics, the present findings contribute to a better understanding of the effects of sex differences on the human brain.Functional magnetic resonance imaging (fMRI) BOLD signal is commonly localized by using neuroanatomical atlases, which can also serve for region of interest analyses. Yet, the available MRI atlases have serious limitations when it comes to imaging subcortical structures only 7% of the 455 subcortical nuclei are captured by current atlases. This highlights the general difficulty in mapping smaller nuclei deep in the brain, which can be addressed using ultra-high field 7 Tesla (T) MRI. The ventral tegmental area (VTA) is a subcortical structure that plays a pivotal role in reward processing, learning and memory. Despite the significant interest in this nucleus in cognitive neuroscience, there are currently no available, anatomically precise VTA atlases derived from 7 T MRI data that cover the full region of the VTA. Here, we first provide a protocol for multimodal VTA imaging and delineation. We then provide a data description of a probabilistic VTA atlas based on in vivo 7 T MRI data.Anastomotic leak is a serious complication following esophagectomy. The aim of the study was to report our experience with indocyanine green fluorescence angiography (ICG-FA)-PINPOINT® assisted minimally invasive Ivor Lewis esophagectomy (MILE) and assess factors associated with anastomotic leak.
We reviewed consecutive patients undergoing MILE from 2013 to 2018. Intraoperative real-time assessment of gastric conduit was performed using ICG-FA with PINPOINT®. Perfusion was categorized as good perfusion (brisk ICG visualization to conduit tip) or non-perfusion (any demarcation along the conduit).
100 patients (81 males, median age 68 [60-72]) underwent MILE for malignancy in 96 patients and benign disease in 4 patients. There were six anastomotic leaks all managed with endoscopic stent placement. There was no intraoperative mortality and no 30-day mortality in leak patients. Patients with a leak were more likely to be overweight with BMI?&gt;?25 (100% versus 53%, p?=?0.03), have pre-existing diabetes (50ion of the gastric conduit with non-perfusion being independently associated with a leak. While perfusion plays an important role in anastomotic integrity, development of a leak is multifactorial, and ICG-FA should be used in conjunction with the optimization of patient and procedural components to minimize leak rates. https://www.selleckchem.com/products/raptinal.html Prospective, randomized studies are required to validate the interpretation, efficacy, and application of this novel technology in minimally invasive esophagectomies.Multiple medication changes are common after bariatric surgery, but pharmacist assistance in this setting is not well described. This study evaluated the feasibility and effectiveness of a pharmacy-led initiative for facilitating discharge medicine reconciliation after bariatric surgery.
A standardized post-operative pharmacy consult evaluationwas conducted on bariatric surgery inpatients at a single academic center starting 1/2/2019. Retrospective chart review evaluated patient characteristics, medication changes, and 30-day outcomes pre-intervention (7/2018-12/2018) and post-intervention (1/2019-12/2019). Two-sample t tests or binomial tests were used for continuous or categorical variables, respectively; a p-value of?&lt;?0.05 was deemed statistically significant.
A total of 353 patients were identified for study inclusion (n?=?158 pre-intervention, n?=?195 post-intervention) with a mean age of 45years, 87% female, and 71% sleeve gastrectomy. Overall pharmacy consultation compliance was 94% with 77.0gement and significantly increased use of non-narcotic pain medications upon discharge among bariatric surgery patients. Improved protocol adherence is anticipated with program maturity and patient education interventions will be deployed to address outpatient phone calls.
Inpatient pharmacy consultation facilitated rapid alteration to more appropriate therapy for hypertension management and significantly increased use of non-narcotic pain medications upon discharge among bariatric surgery patients. Improved protocol adherence is anticipated with program maturity and patient education interventions will be deployed to address outpatient phone calls.Patient-specific instruments (PSI) have been designed to improve the accuracy of performing opening-wedge high-tibial osteotomies (OW-HTO). This study aims to evaluate the lower limb alignment, by comparing pre-operative desired correction to post-operative achieved correction, the difference in surgical time and number of radiological exposures in OW-HTO using patient-specific instruments (PSI) versus conventional osteotomies and the specific and non-specific complications that occurred.
We performed a single-centre, retrospective, observational study, including 25 consecutive patients undergoing OW-HTO using PSI, from January 2019 to October 2020.
Pre-operatively, the mean hip-knee angle (HKA) was 167°, the mean tibial slope was 7.9° and the mean medial proximal tibial angle (MPTA) was 82.5°. Post-operatively, the mean HKA was 182.2° (180.1-184.7°), the tibial slope was 6.5° (4.2-12.9°) and the MPTA was 92.8° (90.6-93°). In both coronal and sagittal plane, all knees were within 2° from the planned value.
